Square D HDA260801 - 80 A, 600 V, 2-Pole Plug-In Circuit Breaker | AmpState

The Square D HDA260801 is a rugged 2-pole molded case circuit breaker engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. With an 80A rating and a 600V maximum, this plug-in unit blends durability with fast, tool-free installation, making it a trusted choice for demanding electrical installs.

Key advantages that set this breaker apart

• Fast plug-in connection enables quick installation and simple replacement, minimizing downtime during panel maintenance or upgrades.
• Thermal-magnetic trip unit delivers stable, repeatable protection by responding to both overload conditions (thermal) and short circuits (magnetic), helping to prevent nuisance trips while safeguarding your wiring and equipment.
• 2-pole configuration ensures simultaneous disconnection of both hot conductors, enhancing safety and system integrity in multi-wire circuits.
• OEM-compatible design is crafted to work seamlessly with matching Square D loadcenters and panelboards, reducing compatibility concerns during replacements or panel upgrades.
• Versatile application suitable for residential, commercial, and light industrial environments where reliable motor loads, lighting branches, and power circuits require solid protection.

Why this model matters for your project

In panelboards and loadcenters, the HDA260801 acts as the first line of defense against electrical faults. The combination of a high 80A rating and a 600V capacity makes it appropriate for larger branch circuits and equipment feeds without compromising safety. The plug-in design minimizes field labor, which matters when updating older panels or conducting scheduled maintenance in busy facilities.

Ideal use cases

• Upgrading residential service panels to support higher-demand circuits for electric heating, spas, or pool equipment
• Commercial lighting and receptacle branches that require reliable protection against overloads and short circuits
• Small to mid-size industrial feeders protecting motors, conveyors, or control circuits in light manufacturing environments
